John 7:38
He who believes in Me, as the Scripture has said, out of his heart will flow rivers of living water.” Bread Box Aug 9 2010
As the Scripture has said: The reference is not to a single passage (verse), but to the general emphasis of such passages as Deut.18:15; Is.58:11; Zech.14:8; (see also Num.24:7). In contrast (compare) to the small amount of water poured out each day during the feast, this is what caused Jesus to speak up as He, Himself was the “Living Water.” Jesus also spoke of the future that there would be a river of water coming out of those who believed in Christ. Not only will they be satisfied themselves, but they also become rivers so that others may drink and be satisfied (v.39).
This prophecy was fulfilled when the Holy Spirit came on the day of Pentecostal and 120 disciples were filled like rivers of living water. They “experienced” His overflow life inside of them. They felt Jesus and out of their heart, the Spirit, like rivers flow into thousands of people who opened their hearts to Jesus when Peter stood up to preach.
This is how much God so loved you so let Him fill you with His Presence. So trust God today!
